Q: What is the temperature range in the cement kiln?
  • A. 800 to 1050⁰C
  • B. 1050 to 1300⁰C
  • C. 1300 to 1500⁰C
  • D. 1800 to 2100⁰C
Correct Answer: Option C - A cement kiln, a huge in dined rotating furnace, is a continuous stream process vessel, in which the feed and fuel are held in a dynamic balance. As the raw materials – limestone, clay & shale – tumble towards the 1500⁰C flame, the chemical reactions transform them into clinker.
